9. For Notification particulars, choose SQS queue.

This prompts Amazon Safety Lake to create an SQS queue that the subscriber can ballot for object notifications.

10. Select Create.

Set up templates and dashboards for Amazon Safety Lake information

Your subscriber for OpenSearch Ingestion is now prepared. Earlier than you configure OpenSearch Ingestion to course of the safety information, let’s configure an OpenSearch sink (vacation spot to put in writing information) with index templates and dashboards.

Index templates are predefined mappings for safety information that selects the proper OpenSearch subject varieties for corresponding Open Cybersecurity Schema Framework (OCSF) schema definition. As well as, index templates additionally include index-specific settings for a selected index patterns. OCSF classifies safety information into completely different classes resembling system exercise, findings, identification and entry administration, community exercise, utility exercise and discovery.

Amazon Safety Lake publishes occasions from 4 completely different AWS sources: AWS CloudTrail with subsets for AWS Lambda and Amazon Easy Storage Service (Amazon S3), Amazon Digital Personal Cloud(Amazon VPC) Stream Logs, Amazon Route 53, and AWS Safety Hub. The next desk particulars the occasion sources and their corresponding OCSF classes and OpenSearch index templates.

To simply establish OpenSearch indices containing Safety Lake information, we advocate following a structured index naming sample that features the log class and its OCSF outlined class within the identify of the index. An instance is supplied under

ocsf-cuid-${/class_uid}-${/metadata/product/identify}-${/class_name}-%{yyyy.MM.dd}

Full the next steps to put in the index templates and dashboards on your information:

1. Obtain the component_templates.zip and index_templates.zip information and unzip them in your native system.

Part templates are composable modules with settings, mappings, and aliases that may be shared and utilized by index templates.

2. Add the part templates earlier than the index templates. For instance, the next Linux command line exhibits how you can use the OpenSearch _component_template API to add to your OpenSearch Service area (change the area URL and the credentials to acceptable values on your setting):

   ls component_templates | awk -F'_body' '{print $1}' | xargs -I{} curl  -u adminuser:password -X PUT -H 'Content material-Kind: utility/json' -d @component_templates/{}_body.json https://my-opensearch-domain.es.amazonaws.com/_component_template/{}

3. As soon as the part templates are efficiently uploaded, proceed to add the index templates:

   ls index_templates | awk -F'_body' '{print $1}' | xargs -I{} curl  -uadminuser:password -X PUT -H 'Content material-Kind: utility/json' -d @index_templates/{}_body.json https://my-opensearch-domain.es.amazonaws.com/_index_template/{}

4. Confirm whether or not the index templates and part templates are uploaded efficiently, by navigating to OpenSearch Dashboards, select the hamburger menu, then select Index Administration.

5. Within the navigation pane, select Templates to see all of the OCSF index templates.

6. Select Part templates to confirm the OCSF part templates.

7. After efficiently importing the templates, obtain the pre-built dashboards and different elements required to visualise the Safety Lake information in OpenSearch indices.
8. To add these to OpenSearch Dashboards, select the hamburger menu, and below Administration, select Stack Administration.
9. Within the navigation pane, select Saved Objects.

10. Select Import.

11. Select Import, navigate to the downloaded file, then select Import.

12. Verify the dashboard objects are imported accurately, then select Achieved.

All the mandatory index and part templates, index patterns, visualizations, and dashboards at the moment are efficiently put in.

Configure OpenSearch Ingestion

Every OpenSearch Ingestion pipeline may have a single information supply with a number of sub-pipelines, processors, and sink. In our resolution, Safety Lake managed Amazon S3 is the supply and your OpenSearch Service cluster is the sink. Earlier than establishing OpenSearch Ingestion, you could create the next IAM roles and arrange the required permissions:

• Pipeline function – Defines permissions to learn from Amazon Safety Lake and write to the OpenSearch Service area
• Administration function – Defines permission to permit the consumer to create, replace, delete, validate the pipeline and carry out different administration operations

The next determine exhibits the permissions and roles you want and the way they work together with the answer companies.

Earlier than you create an OpenSearch Ingestion pipeline, the principal or the consumer creating the pipeline will need to have permissions to carry out administration actions on a pipeline (create, replace, checklist, and validate). Moreover, the principal will need to have permission to cross the pipeline function to OpenSearch Ingestion. If you’re performing these operations as a non-administrator, add the next permissions to the consumer creating the pipelines:

{
	"Model": "2012-10-17",
	"Assertion": [
		{
			"Effect": "Allow",
			"Resource": "*",
			"Action": [
				"osis:CreatePipeline",
				"osis:ListPipelineBlueprints",
				"osis:ValidatePipeline",
				"osis:UpdatePipeline"
			]
		},
		{
			"_comment": "Substitute {your-account-id} along with your AWS account ID",
			"Useful resource": [
				"arn:aws:iam::{your-account-id}:role/pipeline-role"
			],
			"Impact": "Permit",
			"Motion": [
				"iam:PassRole"
			]
		}
	]
}

Configure a learn coverage for the pipeline function

Safety Lake subscribers solely have entry to the supply information within the Area you chose while you created the subscriber. To provide a subscriber entry to information from a number of Areas, confer with Managing a number of Areas. To create a coverage for learn permissions, you want the identify of the Amazon S3 bucket and the Amazon SQS queue created by Safety Lake.

Full the next steps to configure a learn coverage for the pipeline function:

1. On the Safety Lake console, select Areas within the navigation pane.
2. Select the S3 location akin to the Area of the subscriber you created.

3. Make a remark of this Amazon S3 bucket identify.

4. Select Subscribers within the navigation pane.
5. Select the subscriber OpenSearchIngestion that you simply created earlier.

6. Pay attention to the Amazon SQS queue ARN below Subscription endpoint.

7. On the IAM console, select Insurance policies within the navigation pane.
8. Select Create coverage.
9. Within the Specify permissions part, select JSON to open the coverage editor.
10. Take away the default coverage and enter the next code (change the S3 bucket and SQS queue ARN with the corresponding values):

    {
    	"Model": "2012-10-17",
    	"Assertion": [
    		{
    			"Sid": "ReadFromS3",
    			"Effect": "Allow",
    			"Action": "s3:GetObject",
    			"Resource": "arn:aws:s3:::{bucket-name}/*"
    		},
    		{
    			"Sid": "ReceiveAndDeleteSqsMessages",
    			"Effect": "Allow",
    			"Action": [
    				"sqs:DeleteMessage",
    				"sqs:ReceiveMessage"
    			],
    			"_comment": "Substitute {your-account-id} along with your AWS account ID",
    			"Useful resource": "arn:aws:sqs:{area}:{your-account-id}:{sqs-queue-name}"
    		}
    	]
    }

11. Select Subsequent.
12. For coverage identify, enter read-from-securitylake.
13. Select Create coverage.

You have got efficiently created the coverage to learn information from Safety Lake and obtain and delete messages from the Amazon SQS queue.

The entire course of is proven under.

Configure a write coverage for the pipeline function

We advocate utilizing fine-grained entry management (FGAC) with OpenSearch Service. Once you use FGAC, you don’t have to make use of a website entry coverage; you possibly can skip the remainder of this part and proceed to creating your pipeline function with the mandatory permissions. Should you use a website entry coverage, you could create a second coverage (for this put up, we name it write-to-opensearch) as an added step to the steps within the earlier part. Use the next coverage code:

{
	"Model": "2012-10-17",
	"Assertion": [
		{
			"Effect": "Allow",
			"Action": "es:DescribeDomain",
			"Resource": "arn:aws:es:*:{your-account-id}:domain/*"
		},
		{
			"Effect": "Allow",
			"Action": "es:ESHttp*",
			"Resource": "arn:aws:es:*:{your-account-id}:domain/{domain-name}/*"
		}
	]
}

If the configured function has permissions to entry Amazon S3 and Amazon SQS throughout accounts, OpenSearch Ingestion can ingest information throughout accounts.

Create the pipeline function with needed permissions

Now that you’ve created the insurance policies, you possibly can create the pipeline function. Full the next steps:

1. On the IAM console, select Roles within the navigation pane.
2. Select Create function.
3. For Use instances for different AWS companies, choose OpenSearch Ingestion pipelines.
4. Select Subsequent.
5. Seek for and choose the coverage read-from-securitylake.
6. Seek for and choose the coverage write-to-opensearch (should you’re utilizing a website entry coverage).
7. Select Subsequent.
8. For Position Identify, enter pipeline-role.
9. Select Create.

Hold observe of the function identify; you can be utilizing it whereas configuring opensearch-pipeline.

Now you possibly can map the pipeline function to an OpenSearch backend function should you’re utilizing FGAC. You may map the ingestion function to one in all predefined roles or create your individual with needed permissions. For instance, all_access is a built-in function that grants administrative permission to all OpenSearch capabilities. When deploying to a manufacturing setting, make certain to make use of a task with simply sufficient permissions to put in writing to your Amazon OpenSearch Service area.

Create the OpenSearch Ingestion pipeline

On this part, you employ the pipeline function you created to create an OpenSearch Ingestion pipeline. Full the next steps:

1. On the OpenSearch Service console, select OpenSearch Ingestion within the navigation pane.
2. Select Create pipeline.
3. For Pipeline identify, enter a reputation, resembling security-lake-osi.
4. Within the Pipeline configuration part, select Configuration blueprints and select AWS-SecurityLakeS3ParquetOCSFPipeline.

5. Underneath supply, replace the next info:
   1. Replace the queue_url within the sqs part. (That is the SQS queue that Amazon Safety Lake created while you created a subscriber. To get the URL, navigate to the Amazon SQS console and search for the queue ARN created with the format AmazonSecurityLake-abcde-Predominant-Queue.)
   2. Enter the Area to make use of for aws credentials.

6. Underneath sink, replace the next info:
   1. Substitute the hosts worth within the OpenSearch part with the Amazon OpenSearch Service area endpoint.
   2. For sts_role_arn, enter the ARN of pipeline-role.
   3. Set area as us-east-1.
   4. For index, enter the index identify that was outlined within the template created within the earlier part ("ocsf-cuid-${/class_uid}-${/metadata/product/identify}-${/class_name}-%{yyyy.MM.dd}").
7. Select Validate pipeline to confirm the pipeline configuration.

If the configuration is legitimate, a profitable validation message seems; now you can proceed to the following steps.

8. Underneath Community, choose Public for this put up. Our advice is to pick VPC entry for an inherent layer of safety.
9. Select Subsequent.
10. Evaluate the small print and create the pipeline.

When the pipeline is energetic, you must see the safety information ingested into your Amazon OpenSearch Service area.

Visualize the safety information

After OpenSearch Ingestion begins writing your information into your OpenSearch Service area, you must be capable to visualize the information utilizing the pre-built dashboards you imported earlier. Navigate to dashboards and select any one of many put in dashboards.

For instance, selecting DNS Exercise provides you with dashboards of all DNS exercise revealed in Amazon Safety Lake.

This dashboard exhibits the highest DNS queries by account and hostname. It additionally exhibits the variety of queries per account. OpenSearch Dashboards are versatile; you possibly can add, delete, or replace any of those visualizations to fit your group and enterprise wants.

Clear up

To keep away from undesirable fees, delete the OpenSearch Service area and OpenSearch Ingestion pipeline, and disable Amazon Safety Lake.

Conclusion
